Within the span of last couple of years, the increasing human
interference with v- ious natural ecosystems and higher discharge of
pollutants has presented numerous challenges to the society related to
preserving the nature for a better tomorrow. The challenges also mount
pressure on the scienti?c community to invent technologies that would
provide solutions to the problems that are man made and also decrease
the negative consequences that we are facing because of our own actions.
This edited book attempts to present eight technological innovations
that have shown potential to provide answers to a few challenges. Like
the previous collection, the described innovations in the current volume
also cover a range of areas including water and soil pollution,
bio-sensors and energy. However, it is to be realized that no
combination of technology can be enough to make a sizeable difference.
As I said in my last collection, technological advances have to be
integrated with a change in social behavior. The philosophy of
sustainable development has to be the principle of future planning and
growth. In this collection, I am pleased to include an article on noise
pollution. Noise is a pollutant of our own behavior and can only be
solved by a behavioral change. The change that is either voluntary or
enforced by laws. As an environmental scientist noise is not normally a
pollutant that would come in mind as a leading pollutant.
